BOOMERANG.

Application filed March 28, 1922. Serial No. 547,434.

To all 107mm it may concern.

Be it known that I, GERALD MAOLEAY Bnowwn, a subject of the King of Great Britain and Ireland, and a resident of Liverpool, county of Lancashire, England, have invented a certain. new and useful Improvement in Boolnerangs, of which the following is a specification.

My invention relates to an improved standardized boomerang.

Present-day boomerangs as manufactured will not describe a complete circlenor stay in the air unless they are merely thrown horizontally as gliders, and the object or" my invention is to provide a standard boor erang which when held in a perpendicular position and thrown in an horizontal direction will describe a complete and perfect circle and return at high speed, the boomerang staying in the air at about an even height whilst travelling in a perpendicular position.

In order that my said invention may be the more readily understood, reference to he had to the Following description and accompanying sheetol drawings, wherein Figure 1 is a view showing the convex side of the improved boomerang.

Figure 2 is a view showing the flat side thereof.

Figures 3 and 41- are, respectively, section al views taken on lines m, and y, y of Figure 2.

In the several figures, which are illustrative of a boomerang for right-handed circles (right to left), like letters of reference indi cate corresponding parts. i

In carrying out the invention, the convex side a of the boomerang is leftalmost as it usually is, but the flat side I; of said booinerang is, towards one end thereof, thinned,

or tapered off with and without slight conpropeller action. This sli ht ro Jeller sha ing constitutes the sum and substance of the invention.

In use, the boomerang is grasped by one end sickle-wise and thrown in a perfectly p "pendicular position with. flat side to the it, and at about six feet from the ground, ancithemanner of throwing a ball, the boomerang maintaining its perpendicular position whilst, travelling in the air.

The boomerang can be made for describingeither right to left, or left to right circles, although thrown by the right hand, but a separate boomerang for either flight, but with exactly reverse positions of tapering and throwing, will be required. Either may be thrown successfully by a left or right-handed man.

I claim A boomerang including a sickle shaped body of segmental cross-section throughout, and the flat side of said body being beveled oft at the one end to the rear edge and at the other end being beveled off to the front edge, the said beveled oii parts being fash ioued somewhat concavely.

In testimony whereof I have allixed my signature hereto this 14th day of March, 1922.
